To debug any C/C++ application on the device, first install gdbserver (after an Internet connection has been set up).

To install gdbserver:

1. Using a terminal emulator, open a terminal to the device (SSH, debug console or similar).
2. At the command line, enter opkg update
   • After files are downloaded and extracted successfully, the system displays this message: Updated list of available packages in /var/lib/opkg/mlinux-mtcdt
3. Then enter opkg install gdbserver
   • After files are installed successfully, the system displays these messages:
   Configuring libthread-db1.
   Configuring gdbserver.

Once gdbserver is installed, you must copy your application to the Conduit^® and then run it under gdbserver using  the gdbserver-attach command.  To use gdbserver to run your program on the device:

1. Log on to the target system and run the gdbserver program. Enter this command:    target> gdbserver comm program [args …]
   a. comm: how to communicate with GDB
   b. program: the name of your program
   c. args: its arguments
2. Attach your application to the gdbserver using arm-mlinux-linux-gnueabi-gdb on your development workstation (included with the mLinux^™ toolchain). To do this, enter the command:  (gdb) target remote <target_ip>:<port>
